它里面提供了这么一个方法：PosMessage transact(PosMessage msg)
因为WebService里面方法参数是一个对象，那么我应该怎么调用？我没有此WebService对应的接口噢！
想了大半天，试了许多方法，都没有成功，不知道有大神知道不。
WebService的WSDL文件如下：
<?xml version="1.0" encoding="UTF-8"?>
<definitions name="OrderServerWS" targetNamespace="http://thirdpart.service.dnapay/" xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://thirdpart.service.dnapay/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/">

</input>
<output>
<soap:body use="literal" namespace="http://thirdpart.service.dnapay/"/>
</output>
</operation>
</binding>
<service name="OrderServerWS">
<port name="OrderServerWSPort" binding="tns:OrderServerWSPortBinding">
<soap:address location="http://xxx.xxx.xxx.xxx:8080/OrderServerWS"/>
</port>
</service>
</definitions>
有大神知道吗？还请赐教啦。WebService我是第一次接触，麻烦各位大大多多指教噢。我应该用XFire还是Axis呢？
非常感谢回复的各位，以及进来看小弟问题的各位。
